Microbes Beam Electrons to Each Other Via Mineral "Wires"

Bacteria can use minerals in soil as electrical grids, which helps the microbes generate chemicals they need to survive, a new study says.

The process involves different bacterial species trading electrons—negatively charged subatomic particles.

Electrons are key to all life-forms, from mi... Read More
